Coupled Inductor-based Soft-switched Boost-Ćuk Converter for Microinverter Applications [PDF]
In this study, a novel fully soft-switched high step-up dc-dc converter is proposed. The proposed converter comprises the integration of boost and Ćuk converters with the same input inductor and MOSFET, and series-connected output dc-link voltages.

A new soft switching bridgeless PFC converter with lossless snubber
, 2016 ncreasing use of rectifiers causes harmonics pollution in networks. So use of power factor correction (PFC) in converters is inevitable. For reducing weight and volume of converters, designers try to increase switching frequency. The switching losses and
